Is this an exploit, or intentional game design?
One thing I noticed when doing some quick-maths for a separate topic: Small-grid batteries can hold twice as much energy per power cell as the large-grid battery. 216 kWh (200 kWh in public tests 2 and 3) vs 100 kW. I don't know why I never checked this before, but it could save some space on large grids
Large-grid battery (LB) = 15.625 m^3, 12 MW
Small-grid battery (SB) = 2.25 m^3, 4 MW
LBv / SBv = 6.944... (v for volume)
(6.944... - 3) * 2.25 m^3 = 8.875 m^3 of space saved
But, we still have to account for a means of connecting small grid batteries to a large grid.
2.25 m^3 * SB + 17.875 m^3 = 15.625 m^3 * LB
4 MW * SB = 12 MW * LB
(17.875 m^3 is the volume of small + large connectors. I haven't tested batteries on rotors, does it work for powering the parent grid?)
These equations have an intersection (rounded) at (6.042, 2.014) that is, the volume of 6.042 small batteries and the connectors = the volume 2.014 large batteries, and your MW remain the same. Since we can only have an integer number of batteries, if you replace *at least* 3 large batteries with 3n (n = number of large batteries being replaced) small batteries attached by connectors, you save space while halving the number of power cells you need. You also gain the bonus of having detachable batteries, so you could do a battery swap instead of waiting for your ship to recharge. Which is a great use of all those power cells we just saved.
Small battery refers to the OG small grid battery, *not* the small grid small battery.
By all means, check my math. I'm highly sleep-deprived atm. I probably made a mistake.
